In Iran, there are many investigations about landuse change which usually mention negative side. In this research landuse/land cover change trend investigate with use of landsat image and Markov chain in IDRISI Andes V15 software at the period of 1990, 2004 and 2018, and predicted changes for 2032 in Marvdasht region. There are about 196000 ha, equal to 91%, that used for cultivation, while range land, bare land and urban area are about 20000 ha, respectively 4.9, 2.7 and 1.6 percent of region area. In 28 years, from 1990 to 2018, agricultural and range lands decrease about 9%, while bare lands and urban area increased. At this period bare lands increased from 2.7% to 11.29% of the total region area. In general, the results of this study indicate that in the long-term, agricultural lands are declining and bare land is increasing, Hence immediate management plans are necessary to prevent the destruction of agricultural land.
